Technical Description. (t.b.d.)

BRIEF DESCRIPTION: The following description is based on the original description by Boedijn (1951).

The cap of Amanita neglecta is 40 - 110 mm wide, dirty brown, close to buffy brown, paler near the margin, at first hemispherical, later convex then planar, with a smooth or weakly short-striate margin. The volva is present as more or less angular warts, 0.5 - 3 mm wide, very crowded in the center, darker than the cap, and can be easily lost as the mushroom ages. The flesh is thin, white, 2.5 - 5 mm thick over the stem, rapidly thinning towards the margin. 

The gills are free, dirty white to cream color, and 5 - 9 mm broad at the midpoint. 

The stem is 50 - 110 × 6 - 10 mm, narrowing upward, solid, becoming hollow in age, pallid, close to pinkish buff or somewhat darker, covered with dark scales below the ring. The basal bulb is 10 - 20 mm wide. The ring is pale yellow to about colonial buff, skirt-like, and membranous. The volva is present as dark scales arranged concentrically at the top of the bulb and is often disappearing.

The spores measure 6 - 8.5 µm long and are subglobose to broadly ellipsoid. Our description of the spore shape is dependent on the illustration, not the text.

Amanita neglecta was originally described from Java. 

In the original description, the author considered the possibility that this species was identical to Amanita fritillaria (Berk.) Sacc. The examination of the type of A. fritillaria by Corner & Bas (1962) demonstrated that the spores of that species are proportionately narrower than A. neglecta and subsequent study reported on this site supports that observation.

In selecting species for comparison with A. neglecta we looked for taxa with a dark colored cap, warts darker than the cap color,  and spores dominantly broadly ellipsoid or proportionately broader. In this category, we find A. fritillara f. malayensis Corner & Bas, A. pilosella Corner & Bas, and A. pilosella f. atroconica Corner & Bas. None of these taxa have the pinkish buff stem and pale yellow ring described for A. neglecta. In the forms of A. pilosella, the spores are larger. Therefore the taxa seem to be distinct from A. neglecta but to say more about the morphological relationship requires a modern reexamination of Boedijn's type.
